Strong passwords are your first line of defense against unauthorized access. A good password combines length, complexity, and unpredictability. Our tool uses crypto.getRandomValues—the same cryptographic API used by browsers for secure operations—to generate truly random passwords that are resistant to guessing and brute-force attacks.
What Makes a Password Strong?
Length matters most. Each additional character exponentially increases the number of possible combinations. A 16-character password with uppercase, lowercase, numbers, and symbols has over 95^16 possible combinations— far beyond what attackers can feasibly brute-force. Character variety further increases entropy. Include uppercase, lowercase, numbers, and symbols when the service allows it. Our strength meter and entropy display help you understand how secure your password is.
Use a Password Manager
Even the strongest password is useless if reused across accounts or written on a sticky note. Use a reputable password manager to store unique passwords for each service. Generate a strong master password for your password manager— you can use this tool—and enable two-factor authentication wherever available.
When to Generate New Passwords
Generate a new password when creating new accounts, after a data breach affecting a service you use, or when you suspect compromise. Avoid recycling old passwords. If a service offers passkeys or FIDO2 authentication, prefer those over traditional passwords when possible.
